15 Claims. (Cl. 12-124) This invention relates to toe lasting machinesand is herein illustrated as embodied in a toe lasting machine of thetype shown in an application for United States Letters Patent Serial No.731,686, filed April 29, 1958, in the names of Joseph 0. Faneuf et al.It is to be understood, however, that in its broader aspects theinvention is not limited to embodiment in a toe lasting machine of thisparticular type or to the exact mechanical construction herein shown.

In toe lasting machines of the above-mentioned type, the upper materialsare wiped upwardly around and shaped to the toe end of a last and thenare wiped inwardly over and pressed against the bottom face of an insoleon the last by means of toe embracing wipers. Movement of the wipersheightwise relatively to the toe end of the shoe being lasted iseffected in the aforementioned machine as a result of vertical movementof a wiper head by means of a foot treadle which is also used to urgethe wipers forcibly against the overlasted margin of the uppermaterials, while advancing and closing movements of the wipersrelatively to the wiper head are usually effected manually by means of ahand lever. In some instances, as in the machine illustrated in thementioned application, power operated means are arranged to efiect theadvancing and closing movements of the wipers under the control of thehand lever, while power operated means also under the selective controlof the operator are provided for forcing the wipers against theoverlasted upper materials to provide what is called the bedding downaction.

When toe lasting machines of the above-mentioned type are used for thelasting of shoes with cement, it has been found that the application ofheat and pressure, to the overlasted margin of the upper materials isdesirable inasmuch as it tends to smooth down and iron the lastingmargin as well as to speed up the setting of the cement used to securethe upper in lasted position. In fact, the use of heat and pressure inthis way may even be beneficial, although the upper materials areheld'in lasted position by metallic fastenings, such as tacks orstaples, because of the smoothing and ironing action which is ob-'tained. In view of the diflicu-lty of handling heated wipers as well asthe danger of marking or otherwise damaging the upper at the toe end ofthe shoe, several different types of auxiliary heated pressing membershave been proposed for use in toe lasting machines for applying heat andpressure to the overlasted margin of the upper materials after the toeend of a shoe has been lasted and the lasting margin wiped inwardly overand pressed against the insole by means of cold lasting wipers. Forexample, it has been proposed to place a heated plate on the overlastedmargin of the upper materials, after the lasting wipers have beenelevated, at the conclusion of the lasting operation, and then to bringthe wipers down on this plate to cause it to apply pressure to the uppermaterials; to provide separately operable heated pressing membersarranged to be swung from a remote and inoperative position, inwardlyover the toe end of a shoe after the Wipers have been retracted at theend of the lasting operation and then to cause the heated pressingmembers to exert ironing pressure thereon by means of a foot treadle;and also to arrange a heated presser or auxiliary wiping member so thatit can be forcibly inserted between the wipers of a toe lasting machineand the overlasted upper materials at the toe end of the shoe. Whileeach of these prior arrangements has some merit, none has proved to beentirely satisfactory in actual practice.

It is, therefore, a principal object of the present invention to providein a toe lasting machine of the type here under consideration a noveland improved heated pressing member for applying heat and pressure tothe overlasted margin of the upper materials at the toe'end of a shoewhich is not only of relative simple and inexpensive mechanicalconstruction but which is also easy to operate and especially reliableand efiective in use. With this purpose in view, the herein illustratedmachine, which has a wiper head, toe wipers mounted on the head foradvancing and closing movements relatively thereto from a retractedposition, and wiper operating means including a hand lever for thusadvancing and closing the wipers, and means for elfecting relativeheightwise movement between the wipers and the toe end of a shoe beinglasted, is provided with an auxiliary pressing member carried by thewiper head and mounted for movement relatively thereto in a directionextending lengthwise of the shoe being lasted, together with means underthe control of the operator for selectively connecting the pressingmember to the wiper operating means for movement by the hand lever. Moreparticularly, and in the herein illustrated arrangement, fiuid pressureactuated means under the control of the hand lever are provided foroperating the wiper-s and the auxiliary pressing member, which is heatedin any suitable manner, is normally held in a retracted position againstthe action of means tending to move it in the directionof advance of thewipers, by means of a latch, and means are provided for connecting thisheated pressing member to the wiper operating means when this member andthe wiper operating means are in a predetermined relative position,together with means under the control of the operator, and preferablyoperable in response to elevation of the wiper head, for releasing thelatch thus to cause the pressing member to be moved to saidpredetermined relative position and connected to the wiper operatingmeans. Preferably, and as herein illustrated, novel means are interposedbetween the heated pressing member and the wipers, when they are intheir retracted positions, for reflecting and absorbing heat radiatedfrom the heated member thereby to prevent undue heating of the lastingwipers.

The above and other objects and features of the invention will appear inthe following detailed description of the preferred embodiment thereofwhich is illustrated in the accompanying drawings and will be pointedout in the claims.

Referring to these drawings, and especially to Fig. 5, as has alreadybeen suggested, the novel features of this invention are shown asembodied in a toe lasting machine of the type disclosed in theabove-identified application. Thus the herein illustrated machine has awiper head, indicated generally by the reference character 20, this headbeing adjustably supported on an arm 22 which, in turn, is pivotallymounted, by means of a shaft 24, on the machine frame, an upper portionof which is shown and indicated by the reference character 26. Referringto Fig. 3, the wiper head includes a main portion 28, rotatably mountedon a carriage 30 which is adjustable along guideways formed on the arm22, and a cover 32. Associated with the wiper head are two lastingwipers 34, 34 each mounted on a wiper carrier, one of which is shown inFigs. 4 and 8 and identified by the reference character 36. Connected tothese wiper carriers by means of links 38, 38 is a crosshead 40 havingformed integrally therewith a wiper operating rod 42. The wiper carriersare provided with cam grooves, not shown, which cooperate with rollers,see 44, 44 in Fig. 3, associated with the Wiper head and arranged tocause the wipers to be advanced and closed in response to movement ofthe wiper operating rod to the right from the position in which it isshown in Fig. 3 with the wipers 34 retracted and opened.

Such movements of the rod 42 are effected, in the herein illustratedmachine, as in the machine of the above-mentioned application, by meansof a hand lever 50 which is pivotally mounted, at its lower end, on abracket 52 associated with a part of the machine frame 54, by means of ashaft 56 to which it is secured, this hand lever having at its upper enda handle 58, Fig. 5. Also secured to the shaft 56, on the opposite sideof the bracket 52, is an arm 60 which is connected to one arm 62 of abell-crank lever 64 having a second arm 66, by means of a pair of links68, 70 and a differential lever 72. The bell-crank lever 64 is pivotallymounted on the frame part 54 by means of a rockshaft 74. Thedifierential lever 72 is pivotally mounted on a pin 76 carried by thebifurcated end 78 of the stem of a bleed valve 80. As will be understoodby reference to the abovementioned application, this bleed valve isnormally held against its seat, not shown, by means of a locking lever82, spring 84 and a piston in a cylinder 110. The arm 66 of thebell-crank lever 64 is operatively connected to a block 86, secured tothe left-hand end of the wiper operating rod 42, by means of a link 88,bell-crank lever 90, having arms 92 and 94, Fig. 5, and links 96, 96,Fig. 1. With the valve 80 and pivot pin 76 thus immobilized, the wipers34, 34 may be manually advanced and closed, or retracted and opened, bymeans of the hand lever 50 with its operating handle 58 in a mannerwhich will be readily understood.

In common with the machine of the above-mentioned application, theherein illustrated machine is also provided with power operated means,under the control of the hand lever 50, for advancing and closing thewipers. This power operated means includes a fluid pressure actuator 100having an operating rod 102 which is connected to the arm 62 of thebell-crank lever 64. Also connected to this arm, by means of a yoke-likeblock 104, is the rod 106 of a fluid dashpot piston, not shown,contained within a casing 108. On the end of the handle 58 opposite tothat which is shown in Fig. 5 there is a control member in the form of apush button (not shown) adapted to be moved axially of the handleagainst a yieldable resistance and, as will be understood by referenceto the mentioned application, an initial movement of this push buttonrenders the fluid pressure actuator 199 effective to apply, through itsrod 102, a force on the arm 62 of the bell-crank lever 64 tending toswing the arm in a clockwise direction and thus, through the connectionswhich have already been mentioned, to move the wiper ope-rating rod 42to the right thereby advancing and closing the Wipers.

Such initial movement of the push button also has the effect of closingoff a normally open by-pass, not shown, which is associated with thedashpot piston to afford communication between portions of the dashpotcylinder on the opposite sides of the piston, thus preventing movementof this piston and the other parts which are connected thereto, asexplained above, and of exhausting fluid under pressure from thecylinder 110 thereby releasing the locking lever and the bleed valve tothe action of the spring 84. Now, as the hand lever 50 is swung to theright, the bleed valve 80, which controls flow from one side of thedashpot piston to the other, will be opened to permit movement of thewiper rod through the action of the fluid actuator so that the wiperswill be advanced and closed under power and to an extent determined bythe extent of movement of the hand lever. In other words, and as isfully explained in the mentioned application, a servo or feedback actionis obtained. To retract the wipers, the operator releases the pushbutton, thereby discontinuing the power operaion of the wipers and thenmoves the hand lever to the left. Thus, the operator can advance andclose the wipers manually during the upwipe operation and, when greater6&0112 is needed for overwiping, he can quickly bring the power operatedmechanism into action.

Connected to the outer end of the arm 22 is the upper end of a rod thelower end of which is connected to one arm of a lever 122, Figs. 5 and6. The other end of this lever is connected by means ocf a link 124 toafoot treadle 126 which is pivotally supported on a lower portion 130 ofthe machine frame. By means of this foot treadle, the arm 22 may beswung about its pivotal mounting shaft 24 thereby to effect relativeheightwise movement between the wipers 34, 34 and the toe end of a shoebeing lasted in the machine. Also connected to the lever 122, by meansof a link 132, is the operating rod 134 of a fluid pressure actuator136. As is explained in detail in the mentioned application, thisactuator is adapted to be rendered operative, in response to anadditional movement of the push button on the handle 58, so as to exerta force on the lever 122, rod 120 and arm 22 tending to swing the arm ina clockwise direction thereby to press the wipers firmly against thebottom of the toe end of the shoe being lasted.

For the purposes of this invention, the here-in illustrated machine isprovided with a heated pressing member comprising a metallic block ofthe shape shown in Figs. 1 and 7 and formed integrally with a neckportion 152 which is secured to the right-hand end of a hollow operatingrod 154, Figs. 3 and 8. This hollow rod is slidable within a bore 156formed in the wiper operating rod 42, this bore being cut away toprovide a clearance slot 158, Fig. 3, for a purpose which will presentlyappear. Secured to the left-hand end of the rod 154, between twothreaded adjusting collars 160, 162, is a block 164 to which there ispivotally mounted, by means of a trunnion pin 166, a latch lever 168having an upturned right-hand end 170, Fig. 3. The member 150 ishollowed out at 172 to receive an electrical heating coil 174 (Fig. 7)which is connected to asuit able source of electrical energy, notshown,through a cable 176, Figs. 3, 7 and 8. A thin metal plate178 serves as acover for the open-topped neck portion 152 and for the block 150.Extending upwardly from the top of the member 150, adjacent to itsforward edge, is a narrow ridge of metal 180, Fig. 8.

When the wipers 34, 34 are retracted, the block 86 on the wiperoperating rod 42 engages the collar 162 and moves the heated member 150to the retracted position in which it is shown in Fig. 3. At itsleft-hand end the latch lever 168 has an upwardly extending part 182which is shaped to provide a beveled end 184 and a shoulder 186, Fig. 3,adapted to engage a locking lever 188, Fig. 2. This locking lever ispivotally mounted, by means of a pin 190 on a bracket 192 whichissupported on the carriage 30. This lever has a downwardly extendingend 194 which is connected, by means of a link 196, to the armature 197of a solenoid 198. When this solenoid is energized, the locking lever188 will be swung in a counterclockwise direction, against theresistance of a coil spring 200, which normally holds the lever 188 inthe position shown in Fig. l and as determined by a stop surface 199 onthe bracket 192, thereby releasing the end 182 of the lever 168. A coilspring 202, stretched between a pin 204 on thecarriage 30 and an eye 206secured to the lever 168 tends to swing that lever in a counterclockwisedirection and also to move the block 164 and rod 154 to the right, Fig3. -Such swinging movement of the lever 168 is, however, prevented whenthe parts are in the positions shown in Fig. 3 by means of a bar 208,carried by the bracket. 192 and engaging the lower side of the beveledend 184 on the part 182 of this lever. Movement of the rod 154 by thespring 202 is, of course, prevented by engagement of the collar 162 withthe block 86.

The solenoid 198 is normally deenergized'so that the locking lever 188remains in the position shown in (Fig. 2 when the rod 42 is moved to theright either manually or by the power operated means, to advance andclose the wipers 34, 34, the slot 158 in the lower part of the operatingrod 42 now receiving the neck portion 152 asso ciated with the heatedpressing member 150 which remains in the retracted position in which itis shown in Fig. 3. When the solenoid 198, is energizedpthe lockinglever 188, Fig. 2, is swung in a counterclockwise direction, thusreleasing the lever 168 and the block 164 to the action of the spring202. First, this spring swings the lever 168 in a counterclockwisedirection through a small angle and until its upturned end 170 engagesthe flat lower surface on the block 86 and thenthe block 164, rod 154and heated pressing member 150 are moved to the right until the collar162 engages the end of the block 86 thereby establishing a predeterminedrelation between the heated pressing plate and the wiper operat: ingmechanism in which the upturned end 170 of the latching lever passesbeyond the right-hand end of the block 86. The lever 168 is now swungfurther in a counterclockwise direction to cause its upturned end 170 toenter a'notch 210 in the wiper operating rod, thus connecting the heatedpressing plate thereto for movement with this rod as the wipers are.advanced and closed, either manually or by power, or retiractedmanually,as explained above.

For thus energizing the solenoid 198 any convenient arrangement may beprovided. However, in the herein illustrated machine, this isaccomplished as a result of the elevation of the wiper head 20 by upwardswinging of the arm 22 by the treadle 126. Thus there is mounted onabracket 220, associated with the fluid pressure actuator 136, amicroswitch 222 having an operating plunger 224 and connected in theelectrical line leading from a source of electrical energy, not shown,to the solenoid 198. Mounted on the operating rod 134 of the fluidpressure actuator 136 is a bracket '226carrying an adjustable abutmentscrew 228. As will be apparent, when the treadle 126 is actuated toelevate the wiper head 20, the switch 222 will be closed and thesolenoid 198 energized. When the head is lowered, after the heatedpressing plate has been projected to operative position and connected tothe wiper operating rod 42, in the manner just explained, the switch 222will be opened and the solenoid 198 deenergized, thus permitting thelocking lever 188 to be returned to the operation shown in Fig. 2.Accordingly, when the wipers 34, 34 are fully retracted and the heatedpressing member 150, operating rod 154 and block 164 have returned tothe positions shown in Fig. 3, the lower side of the beveled end 184 ofthe upturned portion 182 of the latching lever 168 will engage the rod208 and be carnmed upwardly while the upper side of this beveled endwill cam the locking lever upwardly, by engagement with a cammingsurface 230 thereon, Fig. 3, thereby permitting the parts to reassumethe locked positions shown in Fig. 3. As will be apparent, even thoughthe solenoid 198 may become energized as a result of elevationof thewiper head while the wipers are fully retracted, no movement of thelatching lever 168 or of the heated pressing member could occur becauseof the engagement of the beveled end 184 of the lever 168 with the rod208 and the engagement of the collar 162 with the block 86.

In order to render the heated pressing member 150 practically elfectiveis is necessary that it be heated to a relatively high temperature,e.g., 400 F. It is, however, extremely undesirable that the lastingwipers 34, 34 become anywhere near as warm. To prevent this fromhappening, there is interposed between the heated pressing member andthe wipers when they are in their retracted positions, Fig. 3, means forabsorbing heat and for reflecting heat away from the wipers. This meanscomprises a housing member 300 shaped as shown in Figs. 1, 4 and 8, andsecured to the wiper carrier body portion 28 by means of bolts 302 andspacer blocks 304. On its lower side, this housing member, which ispreferably formed of aluminum, is provided with a bright surface fordeflecting heat from the heated presser member 150 downwardly and awayfrom the wipers. Also, as can be seen in Fig. 4, the member 300 isformed with two sets of reverse folds 306, 308, 306, 308 through whichair may circulate and thus dissipate to the atmosphere heat absorbed bythe member 300.

Referring to Fig. 8, the heated pressing member 150 is shown in itsprojected and operative position beneath the advanced and closed wipers34, 34. It is also shown in operative engagement with the overlastedmargin M of the upper materials U of a shoe S being lasted in themachine. It will be observed that the narrow ridge of metal 180 whichadjoins the leading edge of the heated pressing member, is spaced quiteclose to the lower face of the Wipers. Accordingly, when the heatedpressing member is urged forcibly down against the overlasted margin ofthe upper materials of the shoe, after yielding in an upward directionslightly, as permitted by a slight looseness of the parts and theflexibility of the neck portion 152, it will be supported firmly by theengagement of the ridge 180 with the wipers. However, this metal-tometalcontact is of such a slight extent in area that little, if any, heat isthus transmitted from'the heated pressing member to the wipers.

The operation of the herein illustrated machine and of the novel andimproved heated pressing member should be apparent from the abovedescription. It will, however, be noted that the heated pressing member,while normally held in an out-of-the-way location, is immediatelyavailable for use and can quickly be brought into operative position andconnected to the wiper operating rod in response to an elevation of thewipers after the overwiping operation has been completed. When thusconnected to the wiper operating rod this heated pressing member may notonly be used for applying direct pressure to the overlasted margin ofthe upper materials but it also may be moved in directions extendinglengthwise of the shoe, either manually or by the power operated means,to provide a definite ironing action which tends to augment theoverwiping action of the wipers. Because of the retention of the heatedpressing member in a retracted position and the provision of the heatreflecting and absorbing member, interposed between the heated pressingmember and the retracted wipers, this heated pressing member may bemaintained at a much higher temperature than otherwise would be possibleand its effectiveness is correspondingly increased. For example, themember 150 can be heated to a temperature of over 400 F. while thetemperature of the wipe-rs 34, 34 does not rise much above 120 F. Also,with the arrangement herein illustrated, accidental projection of theheated pressing member into direct engagement with the upper materialsat the toe end of the shoe being lasted, which might result in burningor in otherwise marring the upper in a location which would be visiblein the finished shoe, is entirely avoided.
